To move towards being more single-tasking, consolidationary, and focused (and thus slightly away from multi-tasking, expansionary, diffused) -- I started a training regimen and a new way of thinking.
I announced it in this video a couple days ago.
The early returns look promising.
Of course, lots of techniques work when you first try them out. Hawthorne effect, etc. Is the technique fragile, robust, antifragile? Is it worth using repeatedly? Is it easy to reboot if things go wrong? Is it trite? How difficult is it to start doing if you've been off of it?
These questions aren't answered yet.
But, the early returns are very good. I'm being careful to do the Declare part of Declare->Complete in a smart way, where I know it's 100% possible to finished what I declared.
The thing I didn't expect about the model is how much faster I work on things once I've declared for something. It's like, my mind knows I'm not stuck doing it, so I move through things like a buzzsaw. I went through about nine months worth of miscellaneous paper mail -- which I'd normally budget a half day for -- in a little over an hour.
It feels almost like I have external accountability once I declare for something. I know it's a direction I want to move in, I'm firmly convinced it's incredibly valuable, and somehow my mind is responding. Before I declare for something, maybe there's procrastination or (metaphorical) kicking and screaming about something. Afterwards, things just happen.
The jury is still out -- still too new to judge. But the basic model looks very promising for where I'm at right now.
